Quality Control

Our 1,3-Bis(Isocyanatomethyl)Benzene is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profile analysis, and physical property verification, to ensure it meets exacting industry standards. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture ingress and polymerization.
